The 49ers have had one of the league's best offensive lines since the arrival of center Jonathan Goodwin in 2011. With his status up in the air this offseason, we look into potential replacements for the 35-year-old free agent with an eye toward future salary cap implications. Could Trent Baalke draft another lineman in the early rounds? The answer is inside.

Just three points from the top of the poll last week, the 49ers took a mighty tumble in the Associated Press Pro32 NFL power rankings after the worst loss of the Jim Harbaugh era dropped them all the way to sixth this week – the lowest San Francisco has been in the poll the entire season.

Apparently getting warmed up to pick up this season where he left off last year, David Akers kicked four of his five field goals in the second half Sunday afternoon to complete a run of 19 consecutive points by the 49ers that allowed San Francisco to rally from a two-touchdown deficit to beat the Denver Broncos and improve to 2-1 in the preseason.

The 49ers weren't going to get into a bidding war for David Baas last summer, and that's another item you can add to the long list of decisions done right by the team's brain trust. Baas is coming back to San Francisco this weekend with the New York Giants, but the Niners didn't miss him this season while saving half the cost on his replacement, Jonathan Goodwin, who turned out to be an upgrade.

Taking a look at the biggest movers among the units and individuals whose stock is rising and falling for the 49ers as the team takes a 6-1 record and five-game winning streak into Sunday's game against the Washington Redskins.

The 49ers began a new week Monday by scoring yet again in free agency, bringing safety Dashon Goldson back to the team on a one-year deal. It's another key pickup for the Niners, who have signed 10 free agents in the past week to significantly improve their roster. But do all of the newcomers really have a place with the team? We take a look at where each stands in the final roster pecking order.
